Two patients with a solitary fibrous tumor of the thoracic spinal cord.

We report two patients with thoracic spinal solitary fibrous tumor (SFT). This report includes a patient with the first secondary SFT arising in the central nervous system from a pleural origin to our knowledge. The diagnosis was confirmed by histological and immunohistochemical analysis. Both patients underwent gross total resection of their tumors and did not show signs of local recurrence. The patient with the secondary lesion later presented with visceral dissemination. We review the reports of spinal SFT and discuss the diagnosis and therapeutic management of this intriguing entity.
